"The visit was productive," a Broncos source told The Denver Post. "The team is hopeful and encouraged by the time spent" with Manning.

Manning's agent didn't accompany him to Denver. Manning initially was expected to announce his decision when free agency opens Tuesday, but ESPN reported late Sunday that will not happen by then.

Manning met this past week with Broncos officials, including executive vice president John Elway. No offer has been made. Still uncertain is Manning's ability to pass a physical exam coming off multiple neck surgeries.

Pro Football Talk identified the Jacksonville Jaguars as a potential landing spot for Tebow, a former first-round pick who was a star player at Nease High School in Ponte Vedra Beach, Fla., and the University of Florida.

Tebow would remain with the Broncos if Manning decides to sign elsewhere.

Manning, a free agent after being released by the Indianapolis Colts, flew to Phoenix on Saturday night for meetings with the Arizona Cardinals. After the Cardinals, Manning reportedly is going to Florida to meet with the Miami Dolphins.

The Denver Post reported that Manning has ruled out the Kansas City Chiefs and Seattle Seahawks.

Meanwhile, Tennessee Titans owner Bud Adams wants to sign Manning and says he will do whatever is necessary to convince the four-time NFL MVP to come to Tennessee, even offering up a job in the front office once his playing career ends.

Adams told The Tennessean on Sunday that he has contacted Manning's agent, Tom Condon, to express his interest and ask for the quarterback to visit the Titans.

"I want Manning," the 89-year-old Adams said. "I'd love to see him in Titan blue after watching him so many years with the Colts. ... I want him. I am ready to do what it takes to get him aboard, and I think he'd be the guy to get us into the playoffs."
